A 7B 4-SP162414 is an oil-impregnated bronze plain bearing with an inner diameter of 1-3/4 inches, an outer diameter of 2 inches, and a length of 1-3/4 inches. It is self-lubricating and designed for inch-based components. The part has a length tolerance of ±0.0075 inches, as specified for components over 1-1/2 inches in length. The inner and outer diameter tolerances are +0.0000 / -0.0015 inches, applicable for sizes up to and including 2-1/2 inches. The bearing is manufactured from sintered bronze and does not require additional lubrication during operation.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
